ltp licazi n led December 4, 1906. Serial No. 346.224l

To all whom it ptrty-cmtceri Be it known that I, CASPER H. IIENZEL, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Heaters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to heaters, and the invention has for its object to provide a simple and inexpensive heater, wherein novel means is employed for baffling the products of comlmstion and subjecting the cold air to a large heated surface.

Another object of this invention is to provide a heater particularly designed as a hall heater, wherein gas is used as a heating medium.

With these and other objects in. view, which will more readily appmtr as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully descri ed and then specifically pointed out in the appended claims.

Referring to the drawing forming parts of this specification, like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a vertical sectional view of the heater, Fig. 2 is a cross sectional view taken on the line w-sc of Fig. 1, and Fig. 3 is a similar View of the burner taken on line f1/ of l ig, 1.

.To put my invention into practice I construct my improved heater of a frusto-cone shaped casing 1 suspended from a box like structure 2, which is suitably secured be.

tween the joists 3 of a floor. The box-like structure carries a conventional form of register 4 and to protect the wood-work surrounding the heater, I use asbestos or similar material 5. In the outer casing 1 is mounted a plurality of I double 'frusto coneshaped casings 6, said casings fitting snugly one upon the other and supported by laterally projecting arms 7 secured to the inner sides of the outer casing 1. The topmost casing 6 is closed, while the lowermost casing is provided with a depending dome 8. In the cas ings 6 are arranged ho: 'zontal baliling plates 9 having openings 9 formed therein, while in the dome 8 is mounted a suitable form of burner 10.,- The burner 10 serves functionally as a mixer, and is provided with perforations 11, and with a central battling partition and plate 12.

Upon the top of the burner 10 is mounted I an inverted cone-shaped deflector 14, while into the lower flared end 15 of said burner, extends a gas supply pipe 16, said pipe passing through the casing 1, and having a suit able valve-'17. The burner 10 is supported within the dome 8 by outwardly extending arms 18 seating in sockets 19 carriedby the inner sides of the dome S. Said dome is provided with a small opening 20 whereby the gas can be ignited at the burner 10 and in order that said opening may be conveniently reached, I provide the casing 1 with an opening 21, although the burner may be ignited from the bottom of said casing.

The uppermost easing -6 is provided with a depending exhaust pipe 22 which passes out of the casing 1 as at The upper end of the exhaust pipe extends into the casing 6 and through a partition 24 mounted therein, which is provided with a central opening 25.

In operation, the cold air is adapted to enter the bottom of the casing 1 and the bottom of the dome 8, but the air which enters the casing 1 is only permitted to escape into the compartments to be heated while the air that enters the dome 8 may assist in the combustion of the gas therein, and after passing through the various casings 6 it exhausts through the pipe 22. The baffling plates 9 withinthe casings 6 bathe the heated air and products of combustion sufiiciently to thoroughly heat the sides of the casings whereby the cold air which passes upwardly between said casings 6 and the casing 1 W111 be subjected to a large area of heated surface before passing-into the box-like structure2. The depending exhaust pipe 22 also serves to heat the air passingupwardly around said pipe, thus deriving the full'ibenefit of the heated air and products of combustion before they are permitted to escape. My invention articularly resides in the casings 6, their ha ing plates, and the novel form of burner used in connection with the same. I do not care to confine myself to the specific construction of the heater disclosed in the accompanying drawing or to the heaters use.

What I claim and desire to secure by Letters Patent, is:

' In a hot air heater, a box-like structure adapted to be suspended beneath a hot air register, a. fmsto-conical outer casing sus IIO pended from said structure, a plurality of! burneron said pipe, and an exhaust ipe comsuperposed communicating frusto-conical municating at its upper end With't e up ercasings supported Within the outer casing, most innercasing'above the baflle p ate the uppermost casing of said inner casin s thereof and extending' doWnWardl in the closed at its upper end, a perforated ba e 'outer casing, substantially as descri ed.
